Figure 2: 1 × 105 T17b eEPCs were seeded on bovine gelatine type B coated wells, plane PCL, or PCL/collagen I nanofiber scaffolds. Results are expressed as increase in metabolic activity in relation to 24 h (a). Absolute results suggest an overall superiority of gelatine coating after 24 h (b) and 72 h (c) compared to PCL and PCL/collagen nanofiber scaffolds regarding metabolic activity. After 72 h, PCL/Coll 5% and 25% appear to be advantageous to pure PCL scaffolds. Statistically significant differences between the different groups are indicated for .
